RECOMMENDATIONS FOR ENGINEERED, SAND-BASED SOILS Urban stormwater systems require dense vegetation in order to function, and these systems make high demands on plants. Vegetation must survive in quickly draining soils. Plants are faced with conditions like high winds, heat, sun, salt, alkalinity and frequent disturbance. When obligate wetland plants are specified for these harsh sites the systems generally fail. North Creek recommends finding inspiration from coastal species and perennials which have adapted to thrive in such environments. This palette offers a refreshing new aesthetic: mid-height vegetation with stunning color, texture, pollinator value and excellent stormwater treatment function. Most importantly, these plants flourish in urban conditions.
